Abstract

Aquaculture is one of fast growing food producing sector in the world. Diseases and out breaks are painstaking as the major problem for this industry. Traditional approaches to control diseases in aquaculture comprise the use of antibiotics and chemical disinfectants, but they are no longer recommended due to the emergence of resistant strains of pathogens and accumulation of residues in the environment and non-target organisms. Although, vaccination is an effective means of disease prevention in fish, it could be expensive, time-consuming and stressful to the fishes. In this context, immunostimulant is a naturally occurring compound that modulates the immune system by increasing the host’s resistance against the diseases that in most circumstances are caused by pathogens, and are widely used in aquaculture. Nowadays using polysaccharides as immunostimulant for controlling aquatic diseases gained great attention due to its less toxic, eco-friendly nature and bioactivity. This review article discussed several marine polysaccharides and their role in controlling the diseases in both fin and shell fish species.
水生疾病管理中的多糖
水产养殖是世界上增长最快的粮食生产部门之一。疾病和突发疾病是这个行业面临的主要问题。控制水产养殖疾病的传统方法包括使用抗生素和化学消毒剂,但由于出现了耐药病原体菌株以及在环境和非目标生物中残留的积累,不再推荐使用这些方法。虽然疫苗接种是一种有效的鱼类疾病预防手段,但它可能是昂贵的,耗时的,并给鱼类带来压力。在这种情况下,免疫刺激剂是一种天然存在的化合物,通过增加宿主对大多数情况下由病原体引起的疾病的抵抗力来调节免疫系统,并广泛用于水产养殖。多糖具有毒性小、生态友好、生物活性强等特点,作为免疫刺激剂防治水生疾病受到广泛关注。本文综述了几种海洋多糖及其在防治鳍类和贝类病害中的作用。
